Multi Use Recreational Utility Vehicle

ABSTRACT

A micro weight enclosure when fully loaded with gear and equipment is capable of being towed by vehicles with gross tow weight ratings of less than 1000 lbs. This enclosure does not utilize a traditional chassis, rather uses common manufacturing of panel assemblies mechanically attached together forming the basic structural elements required for strength at minimal weight and reduced wind drag. 
     The enclosure, being ergonomically optimized, allows enough space to stand in one location, but sit, recline, or lay prone in a most comfortable fashion, and to attend to human hygiene and related activity in a secure protected environment. 
     The independent suspension couples directly to the enclosure lowers the vehicle, reducing wind drag, allowing enclosure leveling, improves ingress, egress, and overall occupant comfort. 
     The enclosure being acceptable for day travel; surfing or partying in urban and rural environments as example, or extended travel; road trips or camping as example.

BACKGROUND OF INVENTION

This invention relates to towable recreational utility vehicles, a camper shell, or more particularly, an enclosure specifically designed for super sub compact vehicles with tow weight ratings of 1000 lbs or less.

Recreational vehicles are generally use to provide human comfort and transport items convenient for individuals or groups engaged in activities remote from a persons primary domicile; hiking, swimming, surfing, camping, hunting, and skiing as examples. As the transportation market moves toward smaller, lighter, more gas efficient vehicle, providing additional occupant comforts and conveniences during these activities becomes marketable.

Various enclosures for recreational vehicles, travel trailers, campers, utility vehicles of multiple sizes, forms, and weights are well known in prior art which utilize; a fully rigid enclosure, a semi-rigid or pop up enclosure using a rigid structure coupled to a tent like structure, or a compliant inflatable structure, all three aforementioned enclosures then being attached to chassis with one or more wheels.

Rigid recreational utility vehicles at or near the 1000 lb gross vehicle weight rating have dry weights of near 1000 lb, as the enclosure does not efficiently provide structure back to the chassis and wheel set, the result is little or no cargo capacity for the towed vehicle. Rigid recreational utility vehicles also cause excessive vehicle drag as the enclosure sits atop a chassis then a top an axled wheel set. Compromises in enclosure height to combat vehicle drag has resulted in poor ergonomics for standing within the vehicle. Further attempts to minimize rigid recreational enclosure while maintaining traditional construction technique has provided for poor sitting and sleeping comfort.

Compliant enclosures contain foldable, inflatable, slide-able or otherwise deployable strategies used to achieve the recreational vehicles function at reduced weight and wind drag levels. These compliant enclosure strategies have numerous drawbacks, paramount is the human effort required to erect and deploy the compliant portion of the enclosure. Additional drawbacks include poor protection from the elements, poor personal security, and poor personal property protection. A further drawback is the size and appearance of deployed semi rigid recreational vehicle making its use limited in many instances, an overnight party at a friends requiring parking on a city street as example.

Using common materials and modern manufacturing techniques for recreational utility vehicles leave owners of sub compact and super sub compact vehicles with tow ratings of less than 1000 lbs few good options for vehicles with rigid enclosures.

BRIEF SUMMARY OF INVENTION

According to the illustrative embodiment of the present disclosure, a rigid recreational utility vehicle is shown which comprises a multi-dimensional optimized enclosure reducing weight, increasing load carrying capacity while improving occupant ergonomics.

It would be advantages to provide a vehicle that, even fully loaded with gear or equipment, could be towed by vehicles with a 1000 pound tow rating or less. As the illustrative embodiment of the present disclosure will show a recreational utility vehicle containing a chassis-less load transfer system comprising an enclosure for structural integrity utilizing modular panels, an integrated tow vehicle coupling system, and a suspension system bridging the structural enclosure to the ground engaging system.

According to a further illustrative embodiment of the present disclosure, a recreational/utility vehicle is shown comprising partitioning within an enclosure optimizing ergonomics, providing for an individual to stand erect, sit, and lie down in full comfort, while the rigid enclosure provides maximum personnel security and full protection from the elements. A further illustrative embodiment of the present disclosure will show partitioning allows for division of the enclosure necessary for human grooming and hygiene activities, provides for work surfaces, and provide shelves and supports.

It would be advantageous to provide for a recreational utility vehicle that has easy ingress, egress, and rigid vehicle stability when entered by occupant. According to a further illustrative embodiment of the present disclosure, a recreational utility vehicle is shown comprising a suspension which provides for the suspension to be locked level utilizing a locking pin, to be dropped flat on the ground utilizing a release nut or by removing the suspension assemblies altogether, or lie level on uneven ground when locking pin and release nut are used together. A further illustration embodiment will show insertion of the suspension lock pin stabilizes the enclosure in its nominal, loaded, travel position.

According to a further illustrative embodiment of the present disclosure, a recreational/utility vehicle is shown which comprises an enclosure optimized for aerodynamics, minimizing aerodynamic drag at highway speeds but not compromising aforementioned functions.

The above mentioned and other features of this invention, and the manner of attaining them, will become more apparent and the invention itself will be better understood by reference to the following description of the embodiments of the invention taken in conjunction with the accompanying drawings.
